The patient did not suffer from impaired hearing or speech, but had difficulty understanding spoken or written words.

He also noted his belief that the Wernicke and Broca ~~areas~~ of the brain were connected and predicted damage to this connection would result in a condition in which the patient could both understand and speak words, but would be unable to use words correctly or repeat them. His prediction of this syndrome was later proven to be correct. In addition, this work also was one of the first to establish the concept of right and left cerebral dominance.	+	Wernicke’s fist major publication entitled ''The Aphasic Symptom Complex (1874'') introduced the concept of cerebral localization and described sensory aphasia for the first time.
